This study investigated the impact of the abolition of the tender years doctrine on custody decisions in divorce cases. This doctrine supported the presumption that the mother is the more suitable parent for young children. In March of 1981, the Supreme Court of the State of Alabama found this doctrine to be unconstitutional. To assess the hypothesis that this ruling had a significant effect on custodyrelated decisions, a sample of court records for divorce cases in an Alabama county was examined as representative of the state on a number of key variables. Overall, no significant differences were found on indicator variables for the comparisons before and after the ruling. There was neither an increase in custody grants to fathers nor an increase in custody requests by fathers.  相似文献

Some psychiatrists misuse theoretical concepts beyond their generally accepted dimensions in an attempt to support a conclusion favorable to a litigant or defendant. In the case presented, the concept of identification with the aggressor was used in an attempt to eliminate or minimize the effect of a confession and to buttress the claim that the confession itself was false. Quotations from the actual reports and testimony are used to reflect both this tactic and the context in which these issues were pursued, including a rather startling admission by the psychiatrist dealing with the thoroughness of his professional effort. A brief history of "identification with the aggressor" is presented, a history which contrasts with its application to rather routine police questioning. Similarly, skepticism is clearly merited when a psychitrist testifies as to truthfulness or falsity of a statement.  相似文献

The authors developed a method of malathion insecticide determination in the cadaveric material (blood and wall of the stomach) including extraction of 5 ml of blood (5 g of fragmented tissue of stomach wall) by hexan; preparative chromatographic purification of extract on silicagel layer L 5/40 mkm in hexan-diethyl ether system 10:2; Gas-liquid chromatographic investigation on column with 5% SE-30 and 5% XE-60 (Chromatograph "Colour-106" with thermionic detector). This method makes it possible to detect 72-76% of malathion added.  相似文献

The authors reviewed at autopsy the causes of death of 274 patients with evidence of intravenous drug abuse who had been admitted to a large public hospital. There were 127 who died from diseases unrelated to intravenous drug abuse, and in 41% of these, chronic alcoholism was implicated. Deaths from overdose syndromes and drug-related organ pathology comprised only 11% of all cases. The mean age at death was 39 years. There was a male/female ratio of 3.6:1. Half of all patients died from infection--72 from acquired immunodeficiency syndrome (AIDS) alone. These findings indicate that persons hospitalized with a history of intravenous drug abuse usually die from causes other than overdose and that AIDS and chronic alcoholism are significant problems. Emphasis should be placed upon detecting "hidden" intravenous drug deaths to provide more accurate statistical information.  相似文献

Certain Biblical passages if interpreted literally can be understood as advocating the use of corporal punishment in disciplining children. The purpose of this research was to determine if persons affiliated with religious denominations which emphasized a literal belief in the Bible would demonstrate less appropriate attitudes with regard to discipline than their counterparts who were affiliated with religious denominations which do not subscribe to a literal interpretation of the Bible. The sample consisted of 881 persons who were members of denominations classified as literal or nonliteral believers. Statistically significant differences were noted on the Physical Punishment Scale of the Adult Adolescent Parenting Inventory with persons, regardless of gender or their level of education, who were members of churches subscribing to a literal belief in the Bible preferring the use of corporal punishment over alternate methods of discipline as compared to their nonliteral counterparts.  相似文献

A risk marker analysis of assaulted wives   总被引:1,自引:0,他引:1  
In the wife assault literature, a number of risk markers have been identified. Using the data of the female respondents to the National Family Violence Survey (n = 699), a multivariate analysis was performed to examine which risk factors best differentiated between women involved in nonviolent relationships, verbally aggressive relationships, relationships exhibiting minor physical aggression and severely violent relationships. High levels of marital conflict and lower socioeconomic status emerged as the primary predictors of an increased likelihood of wife assault. Research implications are discussed.  相似文献
